Hello, So I tried following some builds : shield throw and clash. I tried shield throw first. The guide recommended the unique charm sundered night so I try to craft the weapon: not possible. Fine, ill farm the boss. Once I found the axe, I tried to craft the unique charm. Doesn't work either. Fine again, ill try the clash build with griswold's opus.... And again, the unique charm is not craftable ???? What makes a unique charm craftable ? Any tips on finding those ? Which one are you using in the meantime ?
